To solve each of these questions, we need to set up proportions and then solve for x. A proportion states that two ratios are equal.
Let's explain how to solve the first question as an example:
1. x:4 and 45:20
To make the ratios equivalent, we need to set up a proportion:
x/4 = 45/20
To solve for x, we can cross multiply:
20x = 4 * 45
Divide both sides of the equation by 20 to isolate x:
x = (4 * 45) / 20
Simplifying this expression gives us:
x = 180 / 20
Which equals:
x = 9
So, the value of x that makes the pair of ratios equivalent is 9.
Now, with this understanding, you can apply the same steps to solve the remaining questions. Let's list the correct options for each question:
2. 21 to x and 7 to 10
- The correct option is C. 40
3. x to 50 and 16 to 25
- The correct option is A. 32
4. 6 to 8 and 18 to x
- The correct option is C. 24
5. 9/36 and x/4
- The correct option is B. 4
6. 42/22 and 21/x
- The correct option is B. 11
7. x/7 and 5/1
- The correct option is A. 25
8. 20/x and 4/8
- The correct option is B. 40
Remember to set up a proportion equation and then solve for x by cross multiplying and simplifying the equation.
